this comes across as if you are attempting to downplay the importance of this biometric data which is weird considering Altman is paying to get access to just a photo of your eyes.
They are more paying to get you signed up to and using their payment system. The eye thing is not so different to most online banking wanting to see photo id and sometimes a selfie vid that matches to check who you are. Except they get less info - just the image, not your name, dob and id number which banks want.
